While fulfilling responsibilities, the ISO should listen for trigger words suggesting a developing problem, such as:

The correct answer highlights the importance of effective communication and situational awareness within the context of incident management. The phrase "I'm lost" serves as a clear indicator that a team member may be experiencing confusion or difficulty understanding their role or the unfolding situation. This expression can signify a potential gap in situational awareness, which could lead to safety issues or errors in actions during high-stress scenarios.

In the role of an Incident Safety Officer (ISO), being attentive to such trigger words is crucial. They can guide the ISO to intervene and provide the necessary support or clarification to ensure that all personnel are aligned with operational objectives and safety protocols. This active listening can help mitigate risks before they escalate into more significant problems.

Conversely, terms like "Attack," "Please repeat," and "Copy" do not necessarily denote confusion or a lack of understanding. While "Attack" may indicate an urgent situation requiring immediate action, it does not suggest an individual is lost or in need of guidance. "Please repeat" may reflect a request for clarification but does not inherently indicate turmoil. "Copy" suggests acknowledgment rather than confusion. Therefore, "I'm lost" is the most appropriate choice as a trigger word indicating a developing problem requiring immediate attention from the ISO.
